Klemens, I reviewed the data that you brought home. I suspect that the blood pressure monitor at B-4 is defective. Please switch it with the one at B-2 to make sure it isn't in the cable. The garbled output from B-4 was largely responsible for the concatenation of data from succesive patients, since it masked the time stamp by which the program separates one patient from the next. The computer treats a patient who has been multiply registered as multiple individuals and reports separately on each of the entries. Tomorrow I will write a routine to block multiple registration. That should be easy. My tentative thought is that we should write simple routines for the nurses to turn the computer on and off, but if you like we can experiment leaving it on continually. However, since we cannot clear the data files without interrupting mcu, I suspect that random noise will corrupt the data files and garble the monitor analyses. I have started an account of the program in /usr/dci/lib/text/help01. If you don't want it displayed, copy it to some other file and substitute an empty help01 file to forestall error messages. In addition to the ~/lib/text/help01 file, I have placed new ~/lib/src ~/lib/shell and ~/lib/bin directories with various improvements on the attached floppy.
